This large prospective collection of blood samples was undertaken to determine inflammatory status during pre-eclamptic and normotensive pregnancies. Our results support a tendency towards increased inflammation in pre-eclampsia, but the measured cytokines are not eligible for prediction, monitoring or diagnosing pre-eclampsia.

Sodium-glucose cotransporter 2 (SGLT2) inhibition reduces cardiovascular morbidity and mortality in individuals with type 2 diabetes. Beneficial effects have been attributed to increased ketogenesis, reduced cardiac fatty acid oxidation and diminished cardiac oxygen consumption. We therefore studied whether SGLT2 inhibition altered cardiac oxidative substrate consumption, efficiency, and perfusion. <p>13 individuals with type 2 diabetes were studied after four weeks treatment with empagliflozin and placebo in a randomized, double-blind, placebo-controlled crossover study. Myocardial palmitate and glucose uptake were measured with ¹¹C-palmitate and ¹⁸F-FDG PET/CT. Oxygen consumption and myocardial external efficiency (MEE) were measured with ¹¹C-acetate PET/CT. Resting and adenosine stress myocardial blood flow (MBF) and myocardial flow reserve (MFR) were measured using ¹⁵O-H₂O PET/CT. </p> <p>Empagliflozin did not affect myocardial FFA uptake but reduced myocardial glucose uptake by 57% (p<0.001). Empagliflozin did not change myocardial oxygen consumption or MEE. Empagliflozin reduced resting MBF by 13% (p<0.01), but did not significantly affect stress MBF or MFR.</p> <p>In conclusion, SGLT2 inhibition did not affect myocardial FFA uptake, but channeled myocardial substrate utilization from glucose towards other sources and reduced resting MBF. However, the observed metabolic and hemodynamic changes were modest and most likely contribute only partially to the cardioprotective effect of SGLT2 inhibition. </p>

Pharmacokinetic and pharmacodynamic profiles of the rapid-acting insulin analogues lispro and aspart were compared in a randomized, double-blind crossover study of 20 fasting healthy men following a single subcutaneous injection. Either insulin lispro or aspart, 0.05 U/kg-body-weight, was injected subcutaneously and followed by determination of 5-h profiles of plasma glucose, serum C-peptide and insulin concentrations. Lowest glucose concentrations were observed after 50 min in the aspart group (3.2 +/- 0.1 mmol/l versus lispro 3.5 +/- 0.1 mmol/l; p = 0.026) and after 60 min in the lispro group (3.4 +/- 0.1 mmol/l). For blood glucose t min was 59.3 +/- 3.4 min in the aspart and 63.5 +/- 5.3 min in the lispro group (ns). After 40 min a lower C-peptide was determined for aspart (225 +/- 21 pmol/l versus lispro 309 +/- 33 pmol/l; p = 0.031), whereas minimal C-peptide concentrations were reached in both groups after 105 min (lispro 117 +/- 21 pmol/l versus aspart 105 +/- 18 pmol/l). The maximal concentration of insulin was detected in both groups after 40 min (lispro 20.8 +/- 1.1 mU/l versus aspart 24.6 +/- 1.3 mU/l; p = 0.032). For insulin t max was 33.0 +/- 2.6 min in the aspart versus 33.3 +/- 2.6 min in the lispro group (ns). The present results indicate a more rapid absorption of insulin aspart in comparison to insulin lispro. Higher insulin concentrations after subcutaneus injection may be advantageous in meal-related treatment of diabetes.

Key summary points Aim Confusion was more prevalent in frail than in non-frail older patients at hospital admission. Finding COVID-19 and accelerated functional decline were associated among frail older hospitalised patients when compared to non-frail. Message Ninety-day all-cause mortality was 70% among frail hospitalised patients with COVID-19 and 15% among non-frail.
